Saransh Bari

I’m a Software Engineer experienced in building scalable web applications, backend systems, and AI-powered solutions. I work across RESTful APIs, microservices, authentication, database design, caching, and performance optimization to deliver secure, production-ready software.

In my internships as a Full Stack Developer, I developed and integrated scalable RESTful APIs using Node.js, Express.js, MongoDB, and Redis, improving application responsiveness by over 40%. I also implemented authentication flows, middleware, rate limiting, and security best practices, and collaborated with frontend developers to ship full-stack features.

I’m especially excited about Generative AI applications—I've built projects using Retrieval-Augmented Generation (RAG), LangChain, vector databases, and semantic search, including a ContextIQ RAG platform for conversational querying of GitHub repositories and PDFs. I’m comfortable deploying with Docker and cloud platforms (AWS, Vercel, Render) and thrive when I can combine real-time experiences (Socket.IO) with intelligent, LLM-driven functionality.
